Help with side-by-side picture comparison in Windows Movie Maker...?

[IvyandLace]

Help! I can't seem to find out how to do a side-by-side comparison in Windows movie maker-I have a photo of my nephew in a beach chair in his first trip to the beach as well as his most recent trip to the beach and I'd like to have them spin up on the screen, side-by-side...but I can't figure out how!!

Any advice?
